Role of Part 3679561 Thrust Ring Spacer in Engine Systems

In the context of engine systems, the Thrust Ring Spacer, identified by part number 3679561, plays a role in maintaining the proper alignment and spacing between various components. This ensures optimal performance and longevity of the engine.

Interaction with Rocker Lever

The Thrust Ring Spacer is positioned to interact directly with the rocker lever. Its primary function here is to provide the necessary spacing that prevents the rocker lever from coming into undue contact with adjacent components. This spacing is vital for the smooth operation of the rocker lever, allowing it to pivot without interference, thus facilitating efficient valve operation.

Integration within Rocker Lever Assembly

When considering the rocker lever assembly, the Thrust Ring Spacer contributes to the structural integrity of the assembly. By maintaining consistent spacing, it helps in reducing wear and tear on the rocker lever and its pivot points. This is particularly important in high-performance engines where precision and durability are paramount.

Contribution to Rocker Lever Top Level Assembly

In the rocker lever top level assembly, the Thrust Ring Spacer ensures that all components within the assembly are aligned correctly. This alignment is essential for the synchronized movement of the rocker levers, which is critical for uniform valve actuation.
